More of a note to myself than anything, but I feel like the first couple times I read this I totally missed or maybe just forgot the line at the very end where Kendra toys with the idea of someday maybe becoming an Eternal?? idk how I feel about that, and it's kinda weird that it was dropped in literally in the last two pages of the book.
Anyways, I'm always impressed at the sheer amount of action and quests happening in this story; there's never a chance to be bored by any of it, and seeing all the pieces fall into place is immensely satisfying! It definitely gets a touch chaotic at points, but I don't think that detracts from the overall enjoyment of such an epic series finale. ( )

I enjoyed this final book in the series and thought it ended well. There was plenty of action, twists, scary evil creatures and brave heroes. ( )

By far the Keys to the Demon Prison is the strongest book in the Fablehaven series. In it, Mull corrects many of his earlier mistakes, by creating nuanced and interesting characters on all sides. He highlights shifting alliances and the difficulties arising from allying with those currently convenient. Of particular note is the comparison that Mull draws between Seth and the Sphinx in the early part of the book.

The plot is also entertaining, with even more creative settings and creatures. Some of the flaws that plagued the early books, such as villain monologuing, plot that turns out to be largely unnecessary, and repetition of exposition to each character in turn, are still present in Keys to the Demon Prison, but in attenuated form. Mull also tries to actually highlight the strengths and weaknesses of each character, rather than play on gender norms as was the case in early books. ( )

Love all the characters!! Kendra I can relate to the most but I think there's also a bit of Seth in all of us. Brandon Mull's got amazing themes too! I read a lot of trashy stuff before I figured out that there's actually good books out there (I know that probably sounds weird but it's true) but Fablehaven was always an anchor for me. If I ever have kids in the future, I would not hesitate to give this series to them to read. ( )

every character really did great including coulter who ended up dieing in the process. Although am in support of the idea of adding a book or two in the fablehaven series, it has a perfect ending ( )
